This looks OK to me, except for one small detail: I wouldn't use the name "Source entities" for connectors. Instead use "Connector entities" since such entities correspond to actual real connectors on a backplane. A proper source entity would be a sensor or test pattern generator. Which actually can occur with the em28xx since it's used in webcams as well. And a really, really small detail: in the legend the 'interface link' is an arrow, but it should be a line, since there is no direction. The graph itself is fine. As you mentioned on irc, the v4l-subdevX nodes won't be created for this device since all the configuration happens via the standard interfaces. But if they were to be created, then they would appear where they are in this example.
